Expdp fails with Segmentation Fault (core dump), if trying to export more than 14 Schemas like below:
expdp userid=system directory=data_pump_dir dumpfile=test_dump.dmp logfile=test_dump.log schemas= finixr, finixm, finixd, finixds, csmswt, csmswd, csmswg, csmswr, analysisd, analysist, mnsubtab, hecmd, seamd, subpr, scott, webdba

Segmentation Fault (core dumped)
If the last three schema names are removed, the export works fine.
Extracting the stack trace from the core dump with adb, we get:
core file = core -- program ``/oracle/prod/11.2/db1/bin/expdp'' on platform i86pc
SIGSEGV: Segmentation Fault
libc.so.1`sigacthandler+0xee(b, fffffd7fffdf7a10, fffffd7fffdf76b0)
The relevant functions of the call stack seem to be:
Most of the call stack above that is Oracle generic code for catching the segmentation fault signal and trying to handle that cleanly, i.e.:
Settings for swap and ulimit were checked, but nothing relevant was found.
The alert.log shows no entry referring to the issue.
